15. Use the following results from a test for marijuana use, which is provided by a certain drug testing company. Among 142 subjects with positive test results, there are 28 false positive results; among 150 negative results, there are 3 false negative results. If one of the test subjects is randomly selected, find the probability of a false positive or false negative. (Hint: Construct a table.) What does the result suggest about thetest's accuracy? The probability of a false positive...

Only 1 in 1,000 is afflicted with a rare disease for which a diagnostic test has been developed. When a person has the disease , the test returns a positive result 99% of the time. However, when a person does not have the disease, the test shows a positive result only 2% of the time. When a person's test results are positive, in order to validate the results, a second test is given. The second test has the same accuracy...

the probability that a disease- A diagnostic test for a certain disease is applied to individuals kronn to not have the disease. Let x = the number among then test results that are positive (indicating presence of the disease, so is the number of false positives) and free individual's test result is positive lep is the true proportion of test results from disease-free individuals that are positive). Assume that only X is available rather than the actual sequence of test...
